Title: Magnetic head
Inventor: KAWAI KAZUHIKO
IPC: G11B5/127
Filed: 1986-09-12
Abstract: PURPOSE:To decrease film exfoliation at the time of polishing by providing 2nd notches to the back gap part of a ferrite core half body in the direction approximately orthogonal with the notches on the butt surface of the ferrite core half body. CONSTITUTION:The 1st notches 11 are formed to a ferrite core block 10 and the 2nd notches are formed to the block approximately orthogonally with the 1st notches 11. A magnetic metallic film 13 which is ferromagnetic is formed by a sputtering method or the like and thereafter, the magnetic metallic film on joint surfaces 14 is polished away so that the magnetic metallic film remains only in the 1st and 2nd notches. Since the magnetic metallic film exists also in the direction approximately orthogonal with the surface formed with the magnetic metallic film in the above-mentioned manner; therefore the generation of the film rupture is obviated even if the stresses at the time of the polishing are exerted to the block in various directions.

Title: Absorption freezer device
Inventor: NOMURA KAZUO
IPC: F25B15/00
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To provide an absorption freezer device in which a coefficient of performance in an entire device is superior and its size can be made small by a method wherein a flow passage changing-over for thermal operating fluid is improved. SOLUTION: A heat exchanging operation is carried out between a circulating system for circulating refrigerants 7a, 7c and second thermal operating fluid (cold water/hot water) 35b by a condensing/evaporating heat exchanger 111. A flow passage in the circulating system of refrigerants 7a, 7c in respect to the condensing/evaporating heat exchanger 111 is reversed by a pipe passage connection changing-over device 63C, thereby the cold water/hot water 35b is changed over to cooling and heating, respectively. When the cold water/hot water 35b is heated, the first thermal operating fluid (cooling water) 35a for cooling the absorbing function section (absorbing device) 1 is merged with the cold water/hot water 35b. In turn, when a cooling operation is carried out, this flow merging operation is shut off.  Since no changing-over of the flow passage between the cooling water 35a and the cold water/hot water 35b is carried out at a pipe passage connection changing-over device 63C, a mutual heat loss caused by a heat transfer is eliminated, resulting in that the structure can be made small. When the cold water/hot water 35b is heated, the cooling water 35a changed to a high temperature state at the absorbing device 1 is merged with it, so that also during a heating operation performed just after a defrosting operation, a uncomfortable feeling to a human body caused by a delay in heating rising time my not be produced.

Title: Composite material machining drill
Inventor: TAKIGAWA YOSHIHIRO
IPC: B23B51/00
Filed: 1994-09-12
Abstract: PURPOSE: To provide the hole accuracy, suppress the thickness of a processing affected layer and moreover prolong the durable life and prevent the fluffing of carbon fiber at the time of boring composite material in which plural kinds of material including hard-to-cut material are laminated. CONSTITUTION: A back taper part 42 with the outer diameter reduced at the rate of 1.0-2.0mm/100mm is formed at the tip part of a cutting edge part 34 over the axial length L with the rate of 0.5-1.0 to a drill diameter D, and the diameter of a part following the back taper part 42 in the cutting edge part 34, that is, the diameter of a small diameter part 44 is formed to be constant, so that the cutting resistance of a composite material machining drill 10 is ideally reduced. The accuracy of a machined hole is thereby heightened, and the thickness of a machining affected layer is suppressed at the same time. As a result of reducing cutting resistance, the cutting edge hardly wears so as to prolong the service life of the drill, which results in dissolving the fluffing of carbon fiber at the hole outlet on the CFRP22 side.
